where can i refill the CO2 tanks used for growrooms, is this the same CO2 that the firefighters use ? do i refill them at the same place they do ?
Are you running a closed circuit mate? Excessive lighting levels and maintaining VPD levels on the cusp of “too high” If the answer to any of that is anything other than absolutely then just throw the empties away. You’ll cause more harm than good. Co2 is for already professional growers to go that extra 10%. If your not already dropping 30oz per meter then there’s plenty more important things you need to dial in before considering co2.
sealed the 2 rooms completly..put airtight doors..plan to hit a 1400 ppm..ac's and dehumidifiers ready, first time doin this so im not sure how much consumption will take in X amount of time..each room is 3x9 sq (m) with 12x1000w HPS
with only 1400 you may only notice faster growth slightly higher quality .. I have been injecting co2 for about 20 years . the levels i use and notice a major difference in quality and bulk is 2000 . i suggest if it does not cost you to much use co2 for every stage of the growth even sprouting seeds it will shave 2 or 3 weeks off the entire grow ! if its possible to go to high ? i have done it 2700 noticed no difference from 2000. i use burners. when were speaking about co2 in my opinion the worst brand controller on the plant is made by titan controls do not use that trash. idk what controller your using but if your injecting it with a bottle use the fuzzy logic mode. with a burner you cant use that mode . hope your not using those little bubble floats lol
thanks for info man..if i may ask is your output connected to a circulating fan ? i would like to have a generator its more of a space problem rather than a money problem to aquire one..i would need a natural gas or petroleum gas tank also besides the generator...also 2000 seems a bit excess to me based solely on what i read in forums even tho i dont have your experience..or any experience in co2 for that matter, how many lumens-temperature-humidity do you try to maintain ? ..most people i find using agree on the 1200-1500 ppm range but i will most def try to experiment it for better results, do you think you could change something that could allow you to use less ppm with the same efficiency ?
